Studenzen is a former municipality in the district of Südoststeiermark, in the Austrian state of Styria. It lies in the southeastern part of the country, within the broader Südoststeiermark region.
Since the 2015 Styria municipal structural reform, Studenzen is no longer an independent municipality and has been part of the municipality of Kirchberg an der Raab. The reform merged a number of small Styrian municipalities into larger administrative units.
